fabrics.

A. principal object of the invention is to producea machine of thisclass in which a washing member is employed havlng, a specialconstruction which will bring about a repeated passa e of the washingwater through the fibers of the fabric.

A special object of the invention is to accomplish this effect withoutnecessitating the employment of a resilient material for the washingfaces or rubbing faces of the washing members.

One of the objects of the present invention is to produce a washingmachine of this type having a roller or washing member which is verylight and inexpensive and having pockets formed in such. a way as togive a good washing effect.

' Other objects of the invention will appear more fully'from a clearunderstanding of the invention.

The invention consists in the general com bination of parts and in thefeatures hereinafter described, all of which contribute to produce anefficient washing machine.

The preferred embodiment of my invention will be particularly describedin the following specification, while the broad scope of my inventionwill be pointed out in the appended claims, e

In the drawings, Figure 1 is an end elevation of a, washing machineembodying my invention; Fig. 2 is avertical section taken through themachine and showing the cooperating surfaces which produce the washingeffect; and Fig. 3 is a fragmentary View showing a small portion of oneof the shells of the roller.

Referring more particularly to the parts, I shall now describe a smallhand-operated machine embodying the invention, although it must beunderstood that the invention is equally well, applicable topower-driven washing machines.

In the drawings, 1 represents an upper roller which cooperates with alower roller 2, to wash articles passed between the rollers said rollersbeing mounted in a suitable frame 3. The lower roller 2 may have a fixedshaft 4 carrying a crank 5 by means of which the'rollcr may be rotated.The upper roller lis preferably providedwith a shaft, 6, the ends ofwhich are mounted in boxes 7 which may move up and down in guides 8formed in the frame 3; and this upper roller is normally presseddownwardly resiliently by means of springs such as the spring 9,whichexert their pressure upon the boxes 7. The rollers 1 and 2 havecircular heads 10 which are attached in the ends of cylindrical shells11. These shells I]. may be formed of any suitable sheet metal, such aszinc or other pliable metal.- The shells 11 are preferably formedoriginally. as fiat sheets and are then secured to the heads 10 with theends of the sheets coming together to form a butt joint 12. By meansof'dies while ea'chshell is in the form of a sheet, I produce aplurality of pockets or cups 13 which are formed by pressingoroffsetting the material inwardly sons to form cups with bottoms 14 "andslightly converging side walls 15. These cups or pockets are preferablyformed in longitudinal and circumferential rows, and

the material between the rows is preferably ofiset so as toformcorrugations 16 extending longitudinally ,of the rollers, and othercorrugations 17 extending circumferentially around the rollers in such amanner as that indicated in Fig. 3. In the bottoms 14 ofthe cups orpockets of the upper roller I prefer to form perforations 18, andsimilar perforations 19 may be formed in the corrugations 16 of theupper roller. The lower roller is preferably entirely without suchperforations.

In using the machine the frame 3 may be supported on the upper edge 20of a tub or on a shelf, and the textile fabric or cloth 21 which is tobe washed asses up from the tub where it becomes see red with water andpasses between the rollers in the direction indicated by the arrows inFig. 1. The lower roller 2 is rotated meanwhile by means of the crank 5and the pressure of the cloth on the upper roller rotates the upperroller in the opposite direction, that is, so that the adjacent surfacesof the rollers move. in the some directionr The dicated most clearly inFig. 2. As the cloth,

passes l'ietween the rollers, it forcesthe upper roller upwardlycompressing the springs 9 so that the rollers press the materialwithtconsiderable force.- As the material passes toward the line whichjoins the axes of the roller, it becomes corninto the cups or pocketsandthe quantlty of Water in the material WhiCh:!S compressed in thepockets of the upper roller becomes expressed and passes up throu h theperforations 18 into the interior of t e upper roller. A similar actiontakes place at the perforations 19, due to the pressure exerted on thematerial. For this reason the perforations of the upper roller which areapproaching the center line will pass water upwardly as indicated-by thearrows. As the cloth passes out of the space between the rollers, t ecompression exerted on the cloth becomes less and less, and as the clothwithdraws itself from the unperforated cups 1? of the lower roller, apartial vacuum is-formcd within these cups. This tends to draw the waterfrom the fibers of the materialinto the cups of the lower roller andalso tends to draw water inwardly through the adjacent perforationsofthe upper roller, as indicated by the arrows in Fig. 2. In this we thewater is made to circulate with consi erable force through the fibers ofthe material and thereby reduces a veryeficient washing effect. 511'account of the fact that water is constantly flowing upward. in theperforations ofthe'upper roller by ressure, the upper roller in operation wi l accumulate a quantity ofwater so as to form a bath 22 andthe water of this bath is constantly trickling out through.

some of the erfdjgations onto the cloth 21. The line '23 indicates thelevel of this bath inFig. 1. Obviously this level will depend upon thespeed of rotation of the rollers, and if the speed is sufficient thebath will 1 have a high ievel and will .have considerable weight whichmaterially increases the pressuraiof the upper roller on the lowerroller.

F a cloth of considerable thickness be folded up within the folds Inthiswaythe hollow cylindrical form of the roller is utilized to givelightness to the roller when themachine is being transported, and givesweight to the roller when it is in operation. 4 The machine operatesmost effectively on such as a blanket; Where thin cloths are to bewashed, they are preferably folded into considerable thicknessbeforevlveing passed between the rollers. Where ery small or daintyarticles are to be washed, they can of a towel or cloth and the cloththen passed throu h the machine. The washing effect is ufiicient to washall the articles in the interior of the folded cloth. The lower rolleris preferably of somewhat smaller diameter than the upper roller as thethickness of the cloth eing washed virtually increases the di- :ameterof the lower roller. The corrugations 16 and 17 assist in giving therollers a form or embodiment the invention may take, and I do not wishto be limited in the practice of my invention, nor in my claims, to theparticular embodiment set forth above.

What I claim as new is 1. A machine for washing textile fabricscomprising a washing member having a surface with a plurality ofcircumferential rows of cup-shaped pockets, and a second wash- 111gmember cotiperating therewith to compress the wet fabrics into saidpockets, said pockets having perforations to permit the escape of thewater exprcssedirom the fabric in said pockets.

2. A machine for washing textile fabrics comprising a washing memberhaving a surface with a plurality of cup-shaped pockets, and a secondwashing member having a surface with pockets into which the fabric iscompressed and which exert a suction on the fabric as it withdrawstherefrom, cooperating with said first member to compress the wet fabricinto a plurality of said pockets, said pockets having perforations topermit the escape of the water expressed from the fabric.

3. A machine for washing'textile fabrics comprising a washing memberhaving a surfaeeewith a plurality of circumferential rows of cup-shapedpockets, and a second washing member coiiperating therewith to compressthe wet fabric into said pockets, said pockets having perforations topermit the escape of the water expressed from the fabric in saidpockets, and means for resiliently pressing one of said members towardthe other. 4:. A machine for washing textile fabrics comprising a rollerhaving acylindrical shell with an inwardly offset wall forming pocketstherein, and a washing member ,coiiperating therewith to compress thewet fabric into the pockets, said pockets having perforations in thewall thereof permitting the expressed ater to pass into the interior ofsaid shell.
